If you are like mine using safe Macintosh’s OSX default settings to allow system to run & open app only from Third Party Identified OSX App Developers.

You may face problem something like this your Mac’s Security & Privacy preferences will not allow you to open app from Unidentified OSX App Developer.

If you navigate to System Preferences > Security & Privacy > General tab you will see something like this:

So how you will open that particular app that has been blocked by Security & Privacy Settings

Solution 01: You can change settings available in System Preferences > Security & Privacy > General tab under “Allow apps downloaded from:” to “Anywhere’

Important Note: This Solution may not be safest one for health of your OSX system security & privacy settings.

Solution 02: Once you faced with this problem as shown in above image navigate to System Preferences > Security & Privacy > General tab tap on ‘Open Anyway’ button. If apps doesn’t open automatically tap on your respective App again to open it.

Important Note: Sometimes this Solution 02 doesn’t work 100% of time you can follow below solution to open app without problems.

Solution 03: To override your security settings and open the app anyway using finder:

Step 01: First in the Finder locate the app you want to open.

Note: Don’t use Launchpad as Launchpad doesn’t allow you to access the shortcut menu.

Step 02: Press the Control key & then click the app icon > then choose Open from the shortcut menu & Click Open.

Important Note: The app is saved as an exception to your security settings, and you can open it in the future by double-clicking it just as you can any registered developer app.

Your problem of not able to opening particular Macintosh OSX App should be solved by now.
